Boost Your Immune System

Stay healthy with this good-for-you advice from the pros

The nutrition researcher says... Eat yogurt

Research has shown that probiotics, the "good" bacteria found in yogurt, can help boost the activity of immune system cells in your body that destroy viruses and bacteria. People who supplemented with probiotics reduced the length and severity of their colds, taking half as many sick days. Include probiotics in your diet by eating a cup of yogurt per day. Just make sure the package says contains live, active cultures so you get the full health benefits.
